Detailed Description

Macro Definition Documentation

◆ SIP_UNKNOWN_INIT

#define SIP_UNKNOWN_INIT ( )

Initializer for structure sip_unknown_t.

A static sip_unknown_t structure for unknown headers must be initialized with the SIP_UNKNOWN_INIT() macro. For instance,

sip_unknown_t sip_unknown = SIP_UNKNOWN_INIT;
#define sip_unknown(sip)
Access a SIP unknown headers structure sip_unknown_t from sip_t.
Definition sip_protos.h:16077
#define SIP_UNKNOWN_INIT()
Initializer for structure sip_unknown_t.
Definition sip_protos.h:16094

◆ SIPTAG_UNKNOWN

#define SIPTAG_UNKNOWN (   x)

Tag list item for pointer to a unknown headers structure sip_unknown_t.

The SIPTAG_UNKNOWN() macro is used to include a tag item with a pointer to a sip_unknown_t structure in a tag list.

Parameters
xpointer to a sip_unknown_t structure, or NULL.

The corresponding tag taking reference parameter is SIPTAG_UNKNOWN_REF().

◆ SIPTAG_UNKNOWN_STR

#define SIPTAG_UNKNOWN_STR (   s)

Tag list item for string with unknown headers value.

The SIPTAG_UNKNOWN_STR() macro is used to include a tag item with a string containing value of a sip_unknown_t header in a tag list.

Parameters
spointer to a string containing unknown headers value, or NULL.

The string in SIPTAG_UNKNOWN_STR() can be converted to a sip_unknown_t header structure by giving the string s has second argument to function sip_unknown_make().

The corresponding tag taking reference parameter is SIPTAG_UNKNOWN_STR_REF().

Function Documentation

◆ sip_is_unknown()

int sip_is_unknown ( sip_header_t const *  header)
inline

Test if header object is instance of sip_unknown_t.

Check if the header class is an instance of unknown headers object and return true (nonzero), otherwise return false (zero).

Parameters
headerpointer to the header structure to be tested
Return values
1(true) if the header is an instance of header unknown
0(false) otherwise

◆ sip_unknown_copy()

sip_unknown_t * sip_unknown_copy ( su_home_t home,
sip_unknown_t const *  hdr 
)
inline

Copy a list of unknown headers header structures sip_unknown_t.

The function sip_unknown_copy() copies a header structure hdr. If the header structure hdr contains a reference (hdr->h_next) to a list of headers, all the headers in that list are copied, too. The function uses given memory home to allocate all the memory areas used to copy the list of header structure hdr.

Parameters
homememory home used to allocate new structure
hdrpointer to the header structure to be copied

When copying, only the header structure and parameter lists attached to it are duplicated. The new header structure retains all the references to the strings within the old hdr header, including the encoding of the old header, if present.

Example
unknown = sip_unknown_copy(home, sip->sip_unknown);
sip_unknown_t * sip_unknown_copy(su_home_t *home, sip_unknown_t const *hdr))
Copy a list of unknown headers header structures sip_unknown_t.
Definition sip_protos.h:16224
Returns
A pointer to newly copied header structure, or NULL upon an error.

◆ sip_unknown_dup()

sip_unknown_t * sip_unknown_dup ( su_home_t home,
sip_unknown_t const *  hdr 
)
inline

Duplicate a list of unknown headers header structures sip_unknown_t.

Duplicate a header structure hdr. If the header structure hdr contains a reference (hdr->x_next) to a list of headers, all the headers in the list are duplicated, too.

Parameters
homememory home used to allocate new structure
hdrheader structure to be duplicated

When duplicating, all parameter lists and non-constant strings attached to the header are copied, too. The function uses given memory home to allocate all the memory areas used to copy the header.

Example
unknown = sip_unknown_dup(home, sip->sip_unknown);
sip_unknown_t * sip_unknown_dup(su_home_t *home, sip_unknown_t const *hdr))
Duplicate a list of unknown headers header structures sip_unknown_t.
Definition sip_protos.h:16181
Returns
A pointer to the newly duplicated sip_unknown_t header structure, or NULL upon an error.

◆ sip_unknown_format()

sip_unknown_t * sip_unknown_format ( su_home_t home,
char const *  fmt,
  ... 
)
inline

Make a unknown headers from formatting result.

Make a new sip_unknown_t object using formatting result as its value. The function first prints the arguments according to the format fmt specified. Then it allocates a new header structure, and parses the formatting result to the structure sip_unknown_t.

Parameters
homememory home used to allocate new header structure.
fmtstring used as a printf()-style format
...argument list for format
Returns
A pointer to newly makes header structure, or NULL upon an error.

◆ sip_unknown_init()

sip_unknown_t * sip_unknown_init ( sip_unknown_t  x[1])
inline

Initialize a structure sip_unknown_t.

An sip_unknown_t structure for unknown headers can be initialized with the sip_unknown_init() function/macro. For instance,

sip_unknown_t sip_unknown;
sip_unknown_t * sip_unknown_init(sip_unknown_t x[1])
Initialize a structure sip_unknown_t.
Definition sip_protos.h:16112

◆ sip_unknown_make()

sip_unknown_t * sip_unknown_make ( su_home_t home,
char const *  s 
)
inline

Make a unknown headers structure sip_unknown_t.

The function sip_unknown_make() makes a new sip_unknown_t header structure. It allocates a new header structure, and decodes the string s as the value of the structure.

Parameters
homememory home used to allocate new header structure.
sstring to be decoded as value of the new header structure
Returns
A pointer to newly maked sip_unknown_t header structure, or NULL upon an error.

Variable Documentation

◆ sip_unknown_class

msg_hclass_t sip_unknown_class[]
extern

Header class for unknown headers.

The header class sip_unknown_class defines how a SIP unknown headers is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_unknown_t header structure.
